Abstract: A composite utility knife blade and method of making such a blade involves butt joining a tool steel wire to a front edge of an alloy steel backing strip. The wire is electron beam welded to the backing strip to form a composite strip defining a first metal portion formed by the alloy steel backing strip, a second metal portion formed by the tool steel wire, and a weld region joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip is then hardened such that the first metal portion defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion defines a surface hardness within the range of approximately 60 Rc to approximately 75 Rc. The hardened strip is then subjected to at least two tempering and quenching cycles. Then, facets are formed on the edge of the second metal portion to form a straight, tool steel cutting edge along at least one side of the composite strip. The composite strip is then scored at axially spaced locations to form a plurality of score lines, wherein each score line is oriented at an acute angle relative to the axis of the strip, and the plurality of score lines define a plurality of blade sections and scrap sections located between the blade sections. Each scrap section is bent outwardly relative to a plane of the composite strip on one side of a respective score line, the composite strip is then pressed on an opposite side of the respective score line, and the respective blade section is then snapped away from the bent scrap section along the respective score line.

Title: Automatic pressure regulating packaging device for heating food and method thereof
Inventor: LIN DAVID
IPC: B65D81/34
Filed: 2003-07-25
Granted: 2006-03-21
Abstract: The present invention relates to an automatic pressure regulating packaging device for heating food and method thereof. More particularly, it is applied to different types of food packaging boxes or bags which hold frozen or cold-storage food and are sealed up. During the procedure of microwave heating of foods, vapor with high temperature and pressure is produced by an impermeable film coated upon the food-holding area. The vapor is guided to a pressure-regulating area coated by an adversable pressure-regulating film along with a ventilation gap which is opened because of a relative weaker stick at the interface, to regulate partial vapor with over-high pressure. Hereby, food inside the packaging box or bag is heated efficiently in the seal area by circulating high-temperature vapor produced by microwave heat. At the same time, pressure of vapor is regulated to avoid the food packaging box or bag broken without a lapse of much high-temperature vapor and without making food dry and hard.
